Available range 215 – 5080 kW


  • Ammonia Evaporative Condenser with axial fans (CAA)
  • Pre-assembled unit manufactured in W-Tech factory in multiple sections (cells)
  • Available range 215 – 5080 kW
  • Entirely constructed with panels of Magnelis ZM 310 for a better superficial protection
  • The heat exchange coils in evaporative condensers and closed-circuit cooling towers are made of galvanized steel (HDG) and stainless steel as well as all fixing elements, in order to avoid any possible formation of biofilm
  • Direct coupling motor and fans to avoid belt drive systems and relative extra maintenance and regulation
  • High-efficient, well-designed and well-fitted drift eliminators, which greatly eliminate water loss and potential aerosols drift (otherwise easily inhaled), in order to prevent escape of entrained water droplets that might contain
  • Legionella bacteria from the tower
  • Basin surface is sloped to permit complete drainage, emptying during maintenance and avoiding water stagnation, preventing then the growth of bacteria
  • Basin configuration permits also water volume reduction and a lower weight during operation
  • W-COAT special epoxy-poliester paint protection (inside/outside) as optional
